If you like Seafile, you can deploy it in your organization easily. I did that a couple of years ago and it is always working fine under Debian (my favourite distro). However, today I thought of deploying a second server, which will be more important. Following the setup procedure under CentOS, everything was fine (I used this link : https://manual.seafile.com/deploy/using_mysql.html ) but the web interfacewasn't working! I checked Firewalld, SELinux, MariaDB, Logs everywhere... Nothing was really weird, except a new file that I wasn't used to it : gunicorn.conf! Well, that file was a new addition to Seafile starting from 6.3! and it seems that in my configuration, the server was bound to... 127.0.0.1:8000! I just changed that, restarted Seafile and Seahub, and it worked! Hoping that would help someone, someday :)
